Structural Organization of the Body: Chemical level
Smallest Level Atom and molecules
Structural Organization of the Body: Cellular level
Cells: the basic unit of structure and function
Structural Organization of the Body Tissue level (TEST) 4 Types
Group of cells Four Types 1) Epithelial 2) connective 3) muscle 4)nervous
Structural Organization of the Body: Organ level
Groups of 2 or more tissue types
Structural Organization of the Body: Organ system level
related organs; Perform specific function i.e.. Respiratory system
Structural Organization of the Body: Organismal level
Whole organism is human
What are the different Levels of structure and the order smallest to biggest
1) Chemical 2) Cellular 3) Tissue 4) Organ 5) Organ System 6) Organismal
What are the 6 characteristics of living things
1) Organization 2)Metabolism 3)Growth and Development 4) Responsiveness(irritability) 5) Regulation 6) Reproduction
Metabolism
Sum of all chemical reaction in a body
Anabolic reaction
Build Things
Catabolic reaction
Break down things
Growth Vs Development
Growth - things get bigger vs development things become more advanced
Regulation examples
Body temp and Blood Pressure
11 Major Organ Systems of the Body
1)Integumentary System 2)Skeletal System 3) Muscular System 4)Nervous System 5)Endocrine System 6)Cardiovascular System 7)Lymphatic System 8) Respiratory System 9)Digestive System 10)Urinary System 11)Reproductive System
Integumentary System Function and Key Organs
Provides protection and regulates body with Skin/Hair/nails
Skeletal System Function and Key Organs
Provides support and protection with the 206 Bones
Muscular System Function and Key Organs
Produces body movement with muscles
Nervous System Function and Key Organs
Communication through electrical signals helps control other systems Brain spinal cord
Lymphatic System Function and Key Organs
Initiates an immune response to fight infection: Spleen/Thymus/Lymph Nodes
Endocrine System Function and Key Organs
Consists of glands and cell clusters that secrete hormones. Ovaries/Testes/Thymus/Thyroid/Adrenal/Pancreas/Kidney/Pineal body/Pituitary
Cardiovascular System Function and Key Organs
Consists of the heart (a pump); blood; and Blood vessels to transport hones nutrients and pick up waste
Respiratory System Function and Key Organs
Responsible for exchange of gases (oxygen and carbon dioxide) between blood and the air in the lungs. Lungs Larynx
Digestive System Function and Key Organs
Mechanically and chemically digests food materials to absorb nutrients. GI Track; colon; Liver; Gallbladder
What organ is the Accessory digestive to the liver(test)
Gallbladder: The liver secretes bile into the small intestine via the bile duct employing the gallbladder as a reservoir
